Impact of disease severity on gastric residual volume in critical patients

Figure 1 Mean daily gastric residual volume of patients with different Sequential Organ Failure Assessment scores (P < 0. 001). SOFA: Sequential Organ Failure Assessment.

Figure 2 The relationship of mean daily Acute Physiology and Chronic Health Evaluation II score to mean daily gastric residual volume on different study dates (P = 0. 011).

Figure 3 Mean daily gastric residual volume change of survivors and non-survivors during the study period.

Figure 4 Kaplan-Meier estimates of the probability of survival between patients with decreasing change of daily gastric residual volume (PDay12 > 0) and patients without decreasing change of daily gastric residual volume (PDay12 ≤ 0) (P = 0. 017).
